Most of the time when I've had to work on an air-gapped network, I was also provided with a second computer connected to the Internet. I found that to be a good compromise, though getting small code snippets or scripts onto the air-gapped network was a pain since I had to type the whole thing or bug IT to transfer it.
I say most of the time, since I once had to work in a very high-security environment with no Internet-connected computers in the area. I had to leave the secure area to look up things on my phone. It was a nightmare.
This is the ideal design, along with an office whose job it is to manually move data from the public side to the private side. These offices usually have a server on the public and private side to make it seem like it's an automated transfer (like putting a file in Dropbox on the public and then seeing it show up on the private side), but in reality you have a security guard making sure nobody's copying up `MSOfficeOfficialThisTime.msi`.

Couldn't you print the snippet as a QRCode and then scan it on the air gapped system?
